i find it interesting that you say there was no mental anguish from salvia for you, for me i felt like a million elephants were jumping on my chest but the mental anguish came after the hallucinated physical pain left.
my first time taking part in salvia, i was overly adventurous due to much experience with enthoegens.
and so i went right ahead and made salviahusca, actually thats not fair salviahuasca would be a walk in the park compared to the portal-portal i opened that day, no amount of mortal trickery or magic can reverse what was set in motion.
before hand i applied an oil mixture for balancing all chakras on all my chakra points, and took a relatively good dose of prolactin inhibitor.
i smoked a strong aldehyde dehydrogenase inhibitor with peppermint oil and lemongrass oil and applied both transdermally to throat, third eye, and crown chakras, waited 10 minutes and smoked salvia combined with the ALDH inhibitor and peppermint oil and lemongrass oil. the lemongrass was to temporarily make the bbb more permeable. the peppermint for kappa agonism.
it lasted 12 days, the first 3 at about 75-100% threshold effects the 4-8th days at about 50-75% and 9-12th at about 25-50% threshold effects.
for an individual having their first salvia experience this was.... rather jarring
in fact for months afterwords likely to this day, sitting in the exact spot on the specific coach i was sitting on when it happened makes me progressively more antsy the longer i sit their lol
also ever since that i now get profoundly hallucinogenic effects from mustard, especially if coupled with black pepper, and no i don't mean a lot of both i mean normal amounts you put on a sandwich and interestingly i am able to "divine" information and future events wile meditating after eating mustard alone and even more so when combined with black pepper, its much like a combination of the salvia feeling and a strong cannabis hash experience.
i think it could be extremely good idea for somebody with the means to try seeing if they can get kambo to cycle through the aldehyde system, this could possibly allow one to use extremely small doses of kambo to achieve the same effect and reduce damage to the frog both directly and conservation wise, and it could open up the ability to go much farther with kambo than is known how to go, its possible the natives using this already know of the tricks needed to get this working, its also possible they don't, its also possible it wont work at all, considering the structure of the compounds present in the frogs nectar this is likely possible. considering the natives likely strive to reduce pain and danger to the frog if they DON'T know of this yet, and it is found to work, efforts should be made to bring this information to them. considering stories about natives doing 100 dots in a day you know these guys are craving for the pain and would likely be happy to learn how to extend the supply of nectar much farther than what can be done as is.
also i have found that if you don't touch the hot ember to your skin but rather hold it extremely close 1-5 mm away from the skin and do very slow circles on the spot it will cause the same burns as pushing the ember into the skin, without having to introduce carcinogenic compounds to an open wound. and yes this way the skin still peels off after just like pushing it into the skin, also the burns are much more controlled and less messy running of the wound occurs.
i have noticed something, i don't know how to properly express this but i will try, when i have been using this no-touch method i find the burn is TREMENDOUSLY more painful than sticking the ember into the skin, and it goes a little weird here when using this no-touch way on open burns it seals them shut after careful small slow circles are made but before it closes as the ember is dying it seems like my body is DRINKING the energy from the ember, my scientific mind could only grasp perhaps the heating of the blood, and drawing it to the skin/wound reduces the bodies energy load in having to heat itself because blood rushing to a wound is being heated apon its further circulation improving internal temperature, this may have something in common with northern chinese moxibation to help deal with the cold climate.
its very profound when you notice that, as you hold the ember closer (and do small slow circles) your body drinks the energy from the flame faster and in larger amounts per time interval, and when the ember dies, their is a sort of grief that someone has died that you knew this "energy absorption" may only work with specific meridians the one i was working on when i realized what was happening was SP-4. its funny how at the beginning i was thinking oww this burn is stealing my enjoyment by causing pain and then after a wile i came to understand it was the opposite and i was being given from something offering, and this was not a bad thing.
